Abstract

Une méthode dallocation dynamique de ressources partagées dans un réseau de communication consiste à définir, dans un plan temps-fréquence, une supertrame dune durée donnée ?T et dune largeur spectrale ?f, faite dune ou de plusieurs trames, chacune définissant une grille normale de temps-fréquence, un carré, appelé unité de temps-fréquence, constituant le plus petit intervalle de temps et de fréquence allouable à un utilisateur du réseau dans la trame donnée. La méthode consiste aussi à réserver, sur chaque fréquence porteuse dune trame, au moins un bloc dun nombre K, plus grand ou égal à 1, dunités de temps-fréquence, qui peuvent être dynamiquement allouées à un utilisateur pour la communication ou la synchronisation.
